Solve, show property used(associative, communative, and distributive)and show all steps.
15.) (45•32)•0
45*(32*0) Associative Property of Multiplication
45*(0) Zero product property
0 Zero product property
:
17.) 50•(118•20)
50*(20*118) Commutative of multiplication
(50*20)*118 Associative of multiplication
(1000)*118
118,000
19.) (25•78)•4
(78*25)*4 commutative property of multiplication
78*(25*4) associative property of multiplication
78*(100)
7,800
:
Notice these properties made these problems easier and fun to do, rather than a chore. No calculator or scratch paper is needed.
Happy Calculating!!!
